    • in a town ,40% are male and 30% are female and rest are children. find the number of children if the total population is 2 lakh.

    _______________________________

    Given:

    • Male are 40%
    • Female are 30%
    • children are 30% [100-(40+30)]
    • Population= 2 lakh

    _______________________________

    To find :

    • Number of children

    _______________________________

    Population of village:

    = 200000

    _______________________________

    Number of male

     = 40\%

    40\% \: of \: 200000

     =  \frac{40} {100} \times 200000

    40 \times 2000

     = 80000

    _______________________________

    Number of female

     = 30\%

     30\% \: of \: 200000

     \frac{30}{100}  \times 200000

     = 30 \times 2000  \\  = 60000

    _______________________________

    total \: number \: of \: male \:and \: female \:  \\  = 80000 + 60000 \\  = 140000

    number \: of \: children \:  \\  = total \: population \:  - (number \: of \: male \:  + number \: of \: female)

    no. \: of \: children \:  \\  = 200000 - 140000

     = 60000
